RAID wizard
The Index entry is used for internal LUN management and cannot be changed.
The Drive No. entry is also used for internal management and you must not
therefore make any changes to this entry
To assign a logical drive to the disk groups shown, select the corresponding
entry in the Physical Drives window under Disk Groups. Start with 0.
Next, define the RAID level you want to assign to the logical unit (LUN). You can
assign various RAID levels to logical drives. For high performance in applica-
tions with mainly sequential access, we advise using RAID level 3. With higher
I/O loads assign RAID level 5.
In the Logical Capacity column, enter the required value for user capacity. The
Physical Capacity required will be entered automatically in accordance with the
RAID level set previously. At RAID level 0, the difference between physical and
logical capacity is zero. At RAID levels 0+1 and 1, the factor is 2. At RAID levels
3 and 5 the factor depends on the number of physical drives. Leave the Write
Cache on the default setting.
Next, set the Stripe Size. Click the drop-down arrow alongside Stripe Size and
scroll down to the size you require.
Due to Expand cap duration and overall system performance a Stripe Size
of 64K is recommended!
